From on-site operation to on-screen management, CET digital twin unlocks efficient operation and maintenance methods for photovoltaic power plants
Date: 2025-12-10Read: 8
Faced with the industrial opportunities brought by energy transformation, the photovoltaic power generation industry is entering a new stage of refined operation from scale expansion. Large scale photovoltaic power stations in China are mostly located in the western regions with abundant solar resources but sparse population. Due to complex geographical and climatic conditions, traditional operation and maintenance models face prominent challenges such as low efficiency, high cost, and slow response in equipment inspection, supervision, and maintenance.
The combination of photovoltaic power generation and digital twin deeply integrates photovoltaic power generation with the new generation of information technology, comprehensively upgrading the operation and maintenance system of photovoltaic power plants with digital and intelligent technologies, and helping photovoltaic power plants achieve safe, reliable, and efficient operation.
In some sections of the 500MW photovoltaic project of Xinjiang Tianfu Group, CETZhongdian TechnologyProvide it withCET Photovoltaic Power Station Smart Photovoltaic System Solution，Integrated digital twin solution、Robot intelligent inspectionUnmanned aerial vehicle inspectionIntelligent video securityTo achieve multiple goals such as precise energy efficiency management, remote centralized monitoring, regional shared services, and unmanned operation of photovoltaic power plants through multiple systems.
After the deployment of the plan, the photovoltaic power station does not require daily manual inspections, and can monitor the equipment's operating status and perform fault detection in real time through the network indoors, significantly saving manpower and material resources, and greatly reducing operation and maintenance costs and difficulties.
From 'on-site running' to 'screen management', comprehensive upgrade of operation and maintenance
In response to the challenges of complex power station management, the solution utilizes digital twin technology to integrate comprehensive data such as electrical and environmental monitoring to achieve 1:1 simulation of the power station, achieving digital and visual upgrades of power station production and operation. Operation and maintenance personnel can remotely monitor the operation status of primary and secondary equipment in the booster station and the power generation of inverters in the photovoltaic area from the "operation and maintenance room" without the need to physically visit the site, achieving the goal of "planning and strategizing without leaving home".
Deploy intelligent inspection robots equipped withinfrared thermal imagerEquipped with visible light dual light cameras, automatic inspection of booster station equipment, real-time monitoring of equipment operation status, accurate identification of hidden dangers such as equipment heating and abnormal instrument readings, achieving all-weather and automated operation and maintenance management.
Based on the characteristics of extensive layout and undulating terrain of photovoltaic power stations, a plan is proposedThe application of drone image processing and component fault detection technology can automatically identify abnormal conditions such as dust, dirt, cracks, obstructions, and hot spots in photovoltaic modules, accurately locate fault points, and push alarm information, greatly reducing manual inspection intensity and improving inspection efficiency and accuracy.
